Information on Finder with BigEndian

[Its-Just-Nans]

Hello,

Just for information: https://rust-lang.zulipchat.com/#narrow/channel/122651-general/topic/Failling.20CI.20with.20.60aarch64_be-unknown-linux-gnu.60.20and.20nightly/with/596468442

Summary

#[test]
fn finder() {
    use memchr::memmem::Finder;
    let finder = Finder::new(&[80, 75, 6, 6]);
    let window = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 80, 75, 6, 6, 0, 0, 0, 0];
    finder.find(&window).unwrap();
}

# works with the old toolchain
cargo +nightly-2026-05-18-x86_64-unknown-linux-gnu miri test --target aarch64_be-unknown-linux-gnu --no-default-features finder

# FAILS with the new toolchain
cargo +nightly-2026-05-19-x86_64-unknown-linux-gnu miri test --target aarch64_be-unknown-linux-gnu --no-default-features finder

# works with the new toolchain BUT WITHOUT the target flag
cargo +nightly-2026-05-19-x86_64-unknown-linux-gnu miri test --no-default-features finder

Note that in all case I'm using the memchr@2.8
